A Quick Guide to the Most Common Commercial Roofing Systems

What type of commercial roofing system should you install? Commercial roofing contractor Progressive Remodeling & Roofing Company shares a quick guide on the most common commercial roofing systems.

Built-Up Roofing

Built-up roofing (BUR) is one of the oldest types of commercial roofing and remains popular to this day. BUR is composed of alternating layers of bitumen and adhesive on top of a specially prepared substrate. Once the layers are dry and firm, the outer layer is covered by gravel or a similar material, which acts as ballast and provides protection against impact damage and heat from the sun.

Modified Bitumen

Modified bitumen is a multilayer roofing system similar to BUR. The main difference is the top layer, which is protected by a cap sheet instead of gravel. Modified bitumen roofs are comparable to BUR in terms of resistance to high winds, foot traffic and punctures, making them the ideal roof replacement choice for rooftops with high foot traffic.

Metal Roofing

Metal is a versatile roofing material that can be used on both sloped and flat roofs. You can choose from options such as galvanized steel, stainless steel and aluminum copper. Metal roofs are lightweight, wind resistant and do not retain heat. Reflective coatings can be applied to improve a metal roofing system’s energy efficiency.


Single-ply roofing systems feature a single layer of outer roofing material laid over the substrate. The seams can be welded with heat or adhesive. Single-ply roofing can be installed loose-laid and weighed down with ballast, fastened at the seams or fully-adhered to the substrate. Single-ply roofing is available in a variety of materials: EPDM (ethylene propylene diene monomer), TPO (thermoplastic olefin) or PVC (polyvinyl chloride). The choice between material and installation method will depend on your commercial property’s roofing requirements.
